Description :
The data set contains spectra of rotational emission of 12CO, 13CO, C18O (J=1-0), CS (2-1), and N2H+ (J=1-0) for 159 low-mass sources from the dense-core catalogue of the Galactic Cold Cores programme (Montillaud et al. 2015, A&A). The spectra were obtained by pointed observations using the Onsala 20m radiotelescope (Sweden). The observation programme aims at characterising low-mass sources, to investigate their role in the star formation process, particularly for low-mass stars.
